Threaded insertRetighteningThread strippingHigher engagement length over screw diameter ratios (ER), are recommended to avoid thread shearing off in applications, where high strength steel screws are tightened into nuts of materials with lower strength. The aim of this study was to determine the ...
The washing machine stopped spinning, so I dismantled it. Here's what I found: I'm thinking it might have become a big battery, as the steel drive shaft was embedded in the alloy drive bracket, which in turn had 6 studs bolting it to the stainless steel drum. It was all enclosed in...
3 ratio is the same (2:3). Therefore, the much broader peak for MCl-AlCl3 electrolyte can only be accounted for by the presence of multiple Al-cluster species which are in fast chemical exchange. We attempted to deconvolve the spectrum of the alkali MCl:AlCl3...
between CAIs and achondrites were found to be typically longer when measured with the26Al-26Mg chronometer than with the Pb-Pb chronometer. This disagreement has been interpreted22as indicating about 4 times lower26Al/27Al ratio in the zone of the solar protoplanetary disk where the angrite ...
According to current development trends for automotive parts, light-weight is a key issue in improving fuel efficiency and CO2 reduction. Compared to steel... DH Park,HH Kwon - 《International Journal of Precision Engineering & Manufacturing》 被引量: 6发表: 2015年 Overall micro-arc oxidation tr...

The PORTA GANTRY is one of our most popular mobile gantry cranes, which leads the field in terms of strength and performance. Completely portable and made from durable and lightweight aluminium, our PORTA GANTRY provides an essential alternative to steel lifting systems. Learn more about why it ...
Carbon fibre tubes can be used to replace steel members in a wide range of engineering applications. Their superior mechanical properties mean that a tube of the same weight as a steel tube can be much stronger, or a tube of the same strength can be much lighter. This might be applicable...
The 2000 series aluminium alloys are qualified for widespread use in lightweight structures, but solidification cracking during fusion welding has been a long-standing issue. Here, we create a zirconium (Zr)-core-aluminium (Al)-shell wire (ZCASW) and emp
(d) Cross–section of the presence of Al3+ in the film also tends to increase the XPS O/(Mg2+ + Al3+) ratio, but this is a minor effect. The presence of hydroxide in the film is in accordance w ith34 who reported that the bulk of the film formed on magnesium is ...
